For the mailman costume we bought a blue shirt and pants at Goodwill, just used a plain black bag. All the stickers we used we got from a local post office! The Mail order bride costume was a simple white tutu, white garter, white stockings, a veil, and then printed out the mail logo on sheets of paper and attached them to the tutu. We got tons of compliments on how creative and unique it was! The best part and the hardest part of the costume was making a bubble-wrap bow to go on the back of the tutu. Every time I tried to sit down it kept popping and I had to fix it multiple times! We loved the costumes so much and got so many compliments we decided to wear them out 2 nights for Halloween! It was below 30 degrees and freezing but we braved the cold and drank plenty of alcohol to keep us warm!
